Gentoo : Security Vulnerabilities, CVEs, CVSS score >= 7

Soko if the code that powers packages.gentoo.org. Prior to version 1.0.2, the two package search handlers, `Search` and `SearchFeed`, implemented in `pkg/app/handler/packages/search.go`, are affected by a SQL injection via the `q` parameter. As a result, unauthenticated attackers can execute arbitrary SQL queries on `https://packages.gentoo.org/`. It was also demonstrated that primitive was enough to gain code execution in the context of the PostgreSQL container. The issue was addressed in commit `4fa6e4b619c0362728955b6ec56eab0e0cbf1e23y` of version 1.0.2 using prepared statements to interpolate user-controlled data in SQL queries.

Gentoo soko is the code that powers packages.gentoo.org. Versions prior to 1.0.1 are vulnerable to SQL Injection, leading to a Denial of Service. If the user selects (in user preferences) the "Recently Visited Packages" view for the index page, the value of the `search_history` cookie is used as a base64 encoded comma separated list of atoms. These are string loaded directly into the SQL query with `atom = '%s'` format string. As a result, any user can modify the browser's cookie value and inject most SQL queries. A proof of concept malformed cookie was generated that wiped the database or changed it's content. On the database, only public data is stored, so there is no confidentiality issues to site users. If it is known that the database was modified, a full restoration of data is possible by performing a full database wipe and performing full update of all components. This issue is patched with commit id 5ae9ca83b73. Version 1.0.1 contains the patch. If users are unable to upgrade immediately, the following workarounds may be applied: (1.) Use a proxy to always drop the `search_history` cookie until upgraded. The impact on user experience is low. (2.) Sanitize to the value of `search_history` cookie after base64 decoding it.

pkg_postinst in the Gentoo ebuild for Slurm through 22.05.3 unnecessarily calls chown to assign root's ownership on files in the live root filesystem. This could be exploited by the slurm user to become the owner of root-owned files.

The Gentoo sci-mathematics/gimps package before 28.10-r1 for Great Internet Mersenne Prime Search (GIMPS) allows local users to gain privileges by creating a hard link under /var/lib/gimps, because an unsafe "chown -R" command is executed.

In Gentoo Portage before 3.0.47, there is missing PGP validation of executed code: the standalone emerge-webrsync downloads a .gpgsig file but does not perform signature verification. Unless emerge-webrsync is used, Portage is not vulnerable.

The urlopen function in pym/portage/util/_urlopen.py in Gentoo Portage 2.1.12, when using HTTPS, does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and modify binary package lists via a crafted certificate.

fence_manual, as used in fence 2.02.00-r1 and possibly cman, allows local users to modify arbitrary files via a symlink attack on the fence_manual.fifo temporary file.

expn in the am-utils and net-fs packages for Gentoo, rPath Linux, and other distributions, allows local users to overwrite arbitrary files via a symlink attack on the expn[PID] temporary file. NOTE: this is the same issue as CVE-2003-0308.1.

Integer overflow in the process_envvars function in elf/rtld.c in glibc before 2.5-rc4 might allow local users to execute arbitrary code via a large LD_HWCAP_MASK environment variable value. NOTE: the glibc maintainers state that they do not believe that this issue is exploitable for code execution

Stack-based buffer overflow in XnView 1.90.3 allows user-assisted remote attackers to execute arbitrary code via a crafted XPM file with a long section string. NOTE: some of these details are obtained from third party information.

The gnu regular expression code in file 4.20 allows context-dependent attackers to cause a denial of service (CPU consumption) via a crafted document with a large number of line feed characters, which is not well handled by OS/2 REXX regular expressions that use wildcards, as originally reported for AMaViS.

Untrusted search path vulnerability (RPATH) in XnView 1.70 and NView 4.51 on Gentoo Linux allows local users to execute arbitrary code via a malicious library in the current working directory.

Untrusted search path vulnerability in Qt-UnixODBC before 3.3.4-r1 on Gentoo Linux allows local users in the portage group to gain privileges via a malicious shared object in the Portage temporary build directory, which is part of the RUNPATH.

Xpdf, as used in products such as gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, and others, allows attackers to cause a denial of service (infinite loop) via streams that end prematurely, as demonstrated using the (1) CCITTFaxDecode and (2) DCTDecode streams, aka "Infinite CPU spins."

Kommander in KDE 3.2 through KDE 3.4.0 executes data files without confirmation from the user, which allows remote attackers to execute arbitrary code.

Cross-site request forgery (CSRF) vulnerability in MediaWiki 1.3.x before 1.3.11 and 1.4 beta before 1.4 rc1 allows remote attackers to perform unauthorized actions as authenticated MediaWiki users.

The patch for integer overflow vulnerabilities in Xpdf 2.0 and 3.0 (CVE-2004-0888) is incomplete for 64-bit architectures on certain Linux distributions such as Red Hat, which could leave Xpdf users exposed to the original vulnerabilities.

Heap-based buffer overflow in psd.c for ImageMagick 6.1.0, 6.1.7, and possibly earlier versions allows remote attackers to execute arbitrary code via a .PSD image file with a large number of layers.

poppassd_pam 1.0 and earlier, when changing a user password, does not verify that the user entered the old password correctly, which allows remote attackers to change passwords for arbitrary users.

Ebuild in Gentoo may change directory and file permissions depending on the order of installed packages, which allows local users to read or write to restricted directories or execute restricted commands via navigating to the affected directories, or executing the affected commands.

SQL injection vulnerability in auth_login.php in Cacti 0.8.5a allows remote attackers to execute arbitrary SQL commands and bypass authentication via the (1) username or (2) password parameters.

Format string vulnerability in wrapper.c in CVS 1.12.x through 1.12.8, and 1.11.x through 1.11.16 allows remote attackers with CVSROOT commit access to cause a denial of service (application crash) and possibly execute arbitrary code via format string specifiers in a wrapper line.

Tomcat before 5.0.27-r3 in Gentoo Linux sets the default permissions on the init scripts as tomcat:tomcat, but executes the scripts with root privileges, which could allow local users in the tomcat group to execute arbitrary commands as root by modifying the scripts.

Integer overflow in the TIFFFetchStripThing function in tif_dirread.c for libtiff 3.6.1 allows remote attackers to execute arbitrary code via a TIFF file with the STRIPOFFSETS flag and a large number of strips, which causes a zero byte buffer to be allocated and leads to a heap-based buffer overflow.

Stack-based buffer overflow in the ELF header parsing code in file before 4.12 allows attackers to execute arbitrary code via a crafted ELF file.
