emacs: CEDET global-ede-mode file loading vulnerability

Untrusted search path vulnerability in EDE in CEDET before 1.0.1, as used in GNU Emacs before 23.4 and other products, allows local users to gain privileges via a crafted Lisp expression in a Project.ede file in the directory, or a parent directory, of an opened file.

krb5: telnet client and server encrypt_keyid heap-based buffer overflow

Buffer overflow in libtelnet/encrypt.c in telnetd in FreeBSD 7.3 through 9.0, MIT Kerberos Version 5 Applications (aka krb5-appl) 1.0.2 and earlier, Heimdal 1.5.1 and earlier, GNU inetutils, and possibly other products allows remote attackers to execute arbitrary code via a long encryption key, as exploited in the wild in December 2011.

LibreDWG v0.10 to v0.12.5 was discovered to contain a heap buffer overflow via the function bit_utf8_to_TU at bits.c.

GNU Binutils format.c bfd_set_format memory corruption

A vulnerability classified as problematic was found in GNU Binutils 2.43/2.44. Affected by this vulnerability is the function bfd_set_format of the file format.c. The manipulation leads to memory corruption. The attack can be launched remotely. The complexity of an attack is rather high. The exploitation appears to be difficult. Upgrading to version 2.45 is able to address this issue. The identifier of the patch is 8d97c1a53f3dc9fd8e1ccdb039b8a33d50133150. It is recommended to upgrade the affected component.

GNU Binutils ld ldelfgen.c link_order_scan memory leak

A vulnerability was found in GNU Binutils 2.43 and classified as problematic. Affected by this issue is the function link_order_scan of the file ld/ldelfgen.c of the component ld. The manipulation leads to memory leak. The attack may be launched remotely. The complexity of an attack is rather high. The exploitation is known to be difficult. The exploit has been disclosed to the public and may be used. It is recommended to apply a patch to fix this issue. The code maintainer explains: "I'm not going to commit some of the leak fixes I've been working on to the 2.44 branch due to concern that would destabilise ld. All of the reported leaks in this bugzilla have been fixed on binutils master."

GNU Binutils nm nm.c internal_strlen buffer overflow

A vulnerability has been found in GNU Binutils 2.43 and classified as problematic. Affected by this vulnerability is the function __sanitizer::internal_strlen of the file binutils/nm.c of the component nm. The manipulation of the argument const leads to buffer overflow. The attack can be launched remotely. The complexity of an attack is rather high. The exploitation appears to be difficult. The exploit has been disclosed to the public and may be used.

binutils: NULL pointer dereference in _bfd_elf_get_symbol_version_string leads to segfault

An illegal memory access flaw was found in the binutils package. Parsing an ELF file containing corrupt symbol version information may result in a denial of service. This issue is the result of an incomplete fix for CVE-2020-16599.

less: crafted data can result in "less -R" not filtering ANSI escape sequences sent to the terminal

In GNU Less before 609, crafted data can result in "less -R" not filtering ANSI escape sequences sent to the terminal.

emacs: command injection vulnerability in htmlfontify.el

An issue was discovered in GNU Emacs through 28.2. htmlfontify.el has a command injection vulnerability. In the hfy-istext-command function, the parameter file and parameter srcdir come from external input, and parameters are not escaped. If a file name or directory name contains shell metacharacters, code may be executed.

emacs: local command injection in ruby-mode.el

An issue was discovered in GNU Emacs through 28.2. In ruby-mode.el, the ruby-find-library-file function has a local command injection vulnerability. The ruby-find-library-file function is an interactive function, and bound to C-c C-f. Inside the function, the external command gem is called through shell-command-to-string, but the feature-name parameters are not escaped. Thus, malicious Ruby source files may cause commands to be executed.

emacs: command execution via shell metacharacters

GNU Emacs through 28.2 allows attackers to execute commands via shell metacharacters in the name of a source-code file, because lib-src/etags.c uses the system C library function in its implementation of the etags program. For example, a victim may use the "etags -u *" command (suggested in the etags documentation) in a situation where the current working directory has contents that depend on untrusted input.

LibreDWG v0.11 to v0.12.5 was discovered to contain a heap buffer overflow via the function bit_write_TF at bits.c.

LibreDWG v0.10 to v0.12.5 was discovered to contain a heap buffer overflow via the function bit_wcs2nlen at bits.c.

GNU Binutils ld libbfd.c bfd_malloc memory leak

A vulnerability was found in GNU Binutils 2.43. It has been declared as problematic. This vulnerability affects the function bfd_malloc of the file libbfd.c of the component ld. The manipulation leads to memory leak. The attack can be initiated remotely. The complexity of an attack is rather high. The exploitation appears to be difficult. The exploit has been disclosed to the public and may be used. It is recommended to apply a patch to fix this issue. The code maintainer explains: "I'm not going to commit some of the leak fixes I've been working on to the 2.44 branch due to concern that would destabilise ld. All of the reported leaks in this bugzilla have been fixed on binutils master."

A heap-based buffer overflow vulnerability exits in GNU LibreDWG v0.12.5 via the bit_read_RC function at bits.c.

emacs: Emacs Lisp code injection via a crafted mailto URI

emacsclient-mail.desktop in Emacs 28.1 through 28.2 is vulnerable to Emacs Lisp code injections through a crafted mailto: URI with unescaped double-quote characters. It is fixed in 29.0.90.

emacs: Shell command injection via a crafted mailto URI

emacsclient-mail.desktop in Emacs 28.1 through 28.2 is vulnerable to shell command injections through a crafted mailto: URI. This is related to lack of compliance with the Desktop Entry Specification. It is fixed in 29.0.90

GNU Binutils ld libbfd.c bfd_putl64 memory corruption

A vulnerability was found in GNU Binutils 2.43. It has been rated as critical. Affected by this issue is the function bfd_putl64 of the file bfd/libbfd.c of the component ld. The manipulation leads to memory corruption. The attack may be launched remotely. The complexity of an attack is rather high. The exploitation is known to be difficult. The exploit has been disclosed to the public and may be used. Upgrading to version 2.44 is able to address this issue. It is recommended to upgrade the affected component. The code maintainer explains, that "[t]his bug has been fixed at some point between the 2.43 and 2.44 releases".

binutils: heap-based buffer overflow in avr_elf32_load_records_from_section() via large section parameter

An out of bounds flaw was found in GNU binutils objdump utility version 2.36. An attacker could use this flaw and pass a large section to avr_elf32_load_records_from_section() probably resulting in a crash or in some cases memory corruption. The highest threat from this vulnerability is to integrity as well as system availability.
